The performance of an action generates the following distribution:

Demand for the company's products	Probability of demand occurring	Rate of return if demand occurs
Weak	0.1	(50%)
Below average	0.2	(5)
Average	0.4	16
Above average	0.2	25
Strong	0.1	60
	1.0

Calculate the expected performance of the action, the standard deviation, and the coefficient of variation. It must be in Excel and with the formulas that were made.
